This test gave me 10 more points than Mensa test I did more than a year ago. I don't believe I have -redacted- points of intelligence. Instead, its a problem of lack of time limit. From the certa... See more

Russian bots attacked Ukraine on International IQ test
This system was corrupt by russian bots. I have an IQ 123 and i am less than average ukrainian by intellect. Once more(!), it is statistically impossible (!) for Ukraine to have an average IQ less than 96 (and to have the number of participants four times(!) larger, than in Russia with it's four times larger population).
Explanation (for those with IQ less than 123): mean percent (pt) of iq test participants (to the population of their countries) is 0.057pt, SD is 0.06pt, median is 0.034pt, Q3 is 0.078pt, IQR is 0.064pt.
Ukraine has 0.29percent of participants (nearest country with more than 1000 participants has 0.05pt - Indonesia). And this 0.29pt for Ukraine is far from this variation range (Z-test near 3.4, Q3 plus 1.5 x IQR is near 0.1748 pt). Thus, this number of participants for Ukraine is IMPOSSIBLE by the natural way (as well as the critically low mean IQ result for country, widely supporting Bologna Process in high education and having 2nd place in CEE for number of IT specialists).
This is the result of massive attack of "pseudo-ukrainian" (possibly - russian via VPN) bots, decreasing the overall score for Ukraine (most possibly as the part of russian info war against Ukraine).

Reply from IQ test (Free) (international-iq-test.com)
Hello Tamas,
Rest assured that if certain users attempt to manipulate the ranking data, their results are not considered in our annual rankings. We take this matter very seriously and have implemented robust internal mechanisms over the years to detect and filter out such anomalies when compiling our yearly statistics.
Please note that this filtering process is applied only during the creation of the annual rankings and not to the "recent results" section displayed on our homepage.
It is also entirely possible for countries with smaller populations to have a higher number of participants. For further details, we invite you to consult the FAQ section titled "Why do some countries with smaller populations have more candidates than other countries with larger populations?" on the rankings page.
As for the high number of Ukrainian test takers, most of them completed the test in Ukrainian. This is largely due to the website ranking higher in search results in Ukrainian than in Russian, which naturally led to more Ukrainian users.
Best regards,
IQ Support Team

Too boring and doesn’t have my age
They don’t have my age. I’m 10 and in elementary. I don’t know why they don’t have my age, maybe because 10 year olds can’t take the test? Anyways I think it would be pretty nice if the test people could include some real world math problems, or writing and reading problems instead of just random patterns.
